She has, to me anyway, that backwoods twang with a harsh delivery that a lot of women here in Oklahoma have. The ones who were "fetched up" have a much softer delivery. She sounds almost East Texas (no offense Texans.) The Piney Woods type of an accent.
You are so right! I couldn't find the words to make my point but the backwoods twang and harsh delivery with that snarl on her face is a perfect description! BTW: I think I have issues LOL!
